FRAME 5-31
Solution to
In case you had difficulty with the square roots given in Frame 5-28, the
Frame 5-30
problems are worked in greater detail below.
a. between 0.006
and 0.007
a.
0.00004
(actual square root is
0.0063245...)
(1) Pair off beginning at the decimal point
b. between 0.02 and
(2) 0.00004. = (00)(00)(40)
0.03
[You must add a zero to the end of the number so that
(actual square root is
the "4" is part of a pair.]
0.0215540...)
(3) Largest perfect square not over 40 is 36. The square root
of 36 is 6.
(4) (low)
(00)(00)(40) (0)(0)(6) 0.006
(5) (high)
(0)(0)(6+1) 0.007
b.
0.0004645775
(1) Pair off beginning at the decimal point
(2) 0004645775. = (00)(04)(64)(57)(75) (00)(04)
[The digits after the first non-zero pair of digits are
dropped.]
(3) Largest perfect square not over 04 is 4. The square root
of 4 is 2.
(4) (low)
(00)(04) (0)(2) 0.02
(5) (high)
(0)(2+1) 0.03
